LAWRENCE CUTLER, OE PITTSBURGH, PENNSYLVANIA.

WRENCH.

Application filed December 7, 1912.

To all whom it may concern:

Be it known that I, Lawnnnon CUTLER, of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and. useful Improvements in Wrenches.

The objects of my invention are: quick action, close adjustment and concentration of stress directly to the bar.

My invention will be more readily understood by reference to the accompanying drawings, forming a part of this specification, and in which- Figure l is a side elevation of a monkey wrench, embodying my invention in its preferred form. Fig. 2 is a front elevation of a monkey wrench illustrating the sliding lock in the movable jaw with teeth in mesh with those on the shank. Fig. 3 is a side elevation of the movable jaw. Fig. i is an end elevation of the movable jaw. Fig. 5 is a plan view of the movable jaw. Fig. 6 is a plan view of the sliding lock. Fig. 7 is a side elevation of the sliding lock. Fig. 8 is an end elevation of the sliding lock. Fig. 9 is a section of the sliding lock on the line A. A. showing the detail of the teeth. Figs. 10 and 11 are enlarged views of the stop spring. Fig. 12 is a side elevation of a bar or S wrench with a movable jaw embodying my invention in a modified form. Fig. 13 is an end view of the bar or S wrench, illustrating the arrangement of the movable jaw. Fig. 14 is a side elevation of a pipe wrench embodying my invention in a modified form. Fig. 15 is a front elevation of a pipe wrench illustrating the slide lock in the said movable jaw with the teeth in mesh in the shank.

Referring now to the drawings: 1 is the head of the monkey wrench; 2 is the shank; 3 is the wrench handle; l is the movable jaw detailed in Figs. 3, I and 5; 5 is the slide lock detailed in Figs. 6, 7, 8 and 9; 6 is the stop spring detailed in Figs. 10 and 11, which is attached to the movable jaw 4, by means of the machine screw 7 in the cavity 8; the stop spring 6 in conjunction with the recess 9 in the slide lock 5, and recess 10 of the movable jaw 4:, and the teeth 11 on the shank 2 acts as a tension stop, thereby eliminating any lost motion in the slide lock 5.

Specification of Letters Patent.

Patented Dec. 23, 1913.

Serial No. 735,508.

The stop spring 6 in conjunction with the walls at the end of recess 9 forms a dead stop for the slide lock 5, thereby keeping the slide lock 5 from being shoved clear through recess 10.

To operate the wrench, move the slide lock 5 to the extreme right of the movable jaw f, when the teeth 19. on the underside of the slide lock 5 will clear the teeth 11 on the shank 2. Adjust the movable jaw 4- to any desired position, then move the slide lock 5 to the extreme left of the movable jaw 1 when the teeth 12 on the underside of the slide lock 5 will engage the teeth 11 on the shank 2, thereby forcing the movable jaw l toward the said head 1. The rivets 14- passing through the slot 13 of the bar or 8 wrench, Fig. 12, hold the movable jaw in position.

Having described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a wrench having a fixed and sliding jaw, teeth crossing the shank on which the sliding jaw moves at an acute angle, a recess on the sliding jaw opening into the sleeve through which the shank passes, and at an acute angle to said shank but directed opposite to the angle of the teeth above described, and a sliding rack catch movable in said recess and having teeth so located as to mesh with the teeth on the shank.

2. In a wrench having a fixed and a slidable jaw with a toothed shank, a dovetailed recess crossin the slide of the movable jaw at the same angle to the shank as the teeth thereon but in the opposite direction and opening into the sleeve through which the shank slides, and a cooperating sliding rack catch having teeth extending along the greater portion of its length on its inner side and adapted to mesh with those on the shank.

3. In a wrench having a toothed shank, a jaw adapted to slide upon said shank, and comprising a dovetailed recess opening into the sleeve through which the shank slides, with a second recess opening into the first one and a spring secured in said second recess and extending into the first one, a rack catch slidable in the first named recess and having teeth adapted to cooperate with those on the shank and a recess upon one edge of signed my name in the presence of two Witthe outer side adapted to recelve the projectnesses. lng end of the spring whereby 1t 15 allowed to slide so as to release its teeth from those LAWVRENGE CUTLER on the shank, but is prevented from passing In the presence ofout of its recess.
